Fibro Fog, Chemo Brain
Symptoms and Causes of Brain Fog
Different people experience brain fog in different ways, but in general, the symptoms of brain fog may include:
The vast majority of people have experienced brain fog on occasion, as it can be brought on by quotidian factors like a night of poor sleep, jet lag , or even an overly heavy meal. It may also be caused by short-term physical and emotional stressors, such as being pregnant or navigating a difficult time at work or school. These cases of brain fog often resolve once the stressor has passed.
When brain fog is severe and persistent, however, it may indicate a more serious cause or one that requires formal treatment. Such causes can range from psychiatric conditions like anxiety , depression , or PTSD ; to physical health conditions like vitamin deficiencies, COVID-19, multiple sclerosis, or cancer. Certain medical treatments, such as benzodiazepines or chemotherapy, may also induce brain fog; indeed, the term “chemo brain” refers to the brain fog that often occurs when undergoing cancer treatment.
Stress is a common cause of brain fog because stress—and especially chronic stress—keeps our nervous system on high alert. When our bodies and brains are operating in survival mode, we may not have the capacity to focus on minor tasks or engage in logical, rational thinking, resulting in persistent fuzziness or frequent feelings of overwhelm.
